Vrv Vrf Air Conditioning Systems

Some people mistakenly believe that vrv and vrf air conditioning systems are two independent hvac systems.

Vrv vrf air conditioning systems.

As a technology leader in the hvac industry daikin had registered the vrv term which stands for variable refrigerant volume 1 as an official trademark. Also referred to as a vrf system variable refrigerant flow is a technology that circulates only the minimum amount of refrigerant needed during a single heating or cooling period. What makes these systems unique is their flexibility. Like ductless minisplits vrfs use refrigerant as the cooling and heating medium.

They can consist of just a couple indoor units to handle some simple zoning or they can consist of up to an almost unlimited number of air handlers and indoor pieces to handle as large of a project as you wish. Originally created in the early 1980s vrv systems were designed by daikin. In reality these two systems use the same exact technology. This sophisticated new vrf hvac technology is capable of providing not only cooling but also heat and even both simultaneously to different areas within the space.

This is able to meet your air conditioning needs for various projects from offices to commercial building. This company was the industry leader at the time so they trademarked the vrv name to describe the system. Eventually vrf is the more common term for these types of systems and this is the term that will be used for the rest of the article. The vrv and vrf mitsubishi aircon system is equivalent to the commercial grade air conditioning system.

Vrf systems unlike conventional chiller based systems allow for varying degrees of cooling in only certain areas reducing energy consumption. The daikin vrv system is a multi split type air conditioner for commercial buildings that uses variable refrigerant flow control developed by daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building. When daikin launched the vrv air conditioning system in 1982 it introduced the world s first use of variable refrigerant volume control. Daikin s vrv variable refrigerant volume systems first emerged in the 1980s pioneering one of the first hvac systems.

All other companies use vrf variable refrigerant flow 2 for their similar hvac systems. Variable refrigerant flow also known as variable refrigerant volume is an hvac technology invented by daikin industries ltd. The term variable refrigerant flow or vrf refers to the system s ability to control the amount of refrigerant flowing to each of these small air handlers. However daikin has copyrighted the term vrv while other aircon brands use vrf to refer to their own hvac systems.

Vrv multi split type air conditioners. To start off vrv and vrf air conditioning systems are technically the same. This refrigerant is conditioned by a single or multiple condensing units and is circulated within the building to multiple indoor units. Vrv vrf systems can be as simple or complex as you would like them to be.
